If the categories are narrower then the rules must be very specific for it to work. In my opinion it should be like this ( maximum for each level):
Beginner: 10 move combo, latw, maatw, atatw, magellan, basic nt combos like crossover - atw (nt), tatw-htw (nt)
Intermediate: 30 move combo, 2-3 move nt combos like tatw-matw (nt), amatw-amatw-amatw (nt), mgtatw, lmatw, beck variations like bltatw, beck palle trick etc
Advanced: Crazy hardcore shit.
Weak foot level? I don't know.

Unusual stuff like datw, sagami atw, new shit, 360 atw could also be beginner i think.
Does anyone agree with this?
